Servo re-tuning?

Hello,

Ive just changed the 2-4 servo seals and rings on the 4L60E VE Commodore/G8 Pontiac.
The reason was that the accelerator has to be feathered to upshift at low speed, and this along with the possible 1-2 accumulator piston and d-ring will be the cause supposedly.

Does it require re-tuning after the servo reco or not?

Thanks.
